Where you grew up, how much money you make, and genetics can all factor into health and nutrition. Because of this complexity, researchers cannot design experiments where they manipulate each of these factors one by one and see what effect that has on health. Instead, scientists rely on observational studies, collecting demographic data and information about the dietary habits of participants including their UPF consumption.<\/p>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">But even collecting data on dietary habits is challenging. \u201cIn nutrition, what makes it even harder is that diet is so extremely complex,\u201d explained <a href=\"https:\/\/scholar.google.com\/citations?user=gsLuYa8AAAAJ&amp;hl=en\" target=\"_blank\" rel=\"noopener\">Filippa Juul<\/a>, a nutritional epidemiologist at New York University.<\/p>\n<\/div>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">We\u2019ve known for a few decades that something about modern, prepackaged foods leads to negative health impacts. In the 1980s, as breakneck globalization ushered in a new world where mass production reached more people than ever before, diets around the world changed, too. In the early 2000s, nutritional epidemiologist Carlos Augusto Monteiro was studying dietary habits of fellow Brazilians. He and his team studied associations between <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/17273628\/\" target=\"_blank\" rel=\"noopener\">breastfeeding and obesity<\/a> and the impact of <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21107500\/\" target=\"_blank\" rel=\"noopener\">income<\/a> and <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/17273647\/\" target=\"_blank\" rel=\"noopener\">education<\/a> on fruit and vegetable consumption. Importantly, Monteiro was also tracking changes in both the prevalence of chronic diseases and changes in Brazilian diets.<\/p>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">One study, in which Monteiro and his colleagues studied data on dietary habits from 1987 to 2003, found that the consumption of traditional foods such as rice and beans had declined while the consumption of processed food items such as store-bought cookies and soda had increased, in some cases by more than <a href=\"https:\/\/www.cambridge.org\/core\/journals\/public-health-nutrition\/article\/increasing-consumption-of-ultraprocessed-foods-and-likely-impact-on-human-health-evidence-from-brazil\/C36BB4F83B90629DA15CB0A3CBEBF6FA\" target=\"_blank\" rel=\"noopener\">200 percent<\/a>. Monteiro and his team had captured, in real time, a trend that has taken place in nearly every developed country in the world: a huge increase in the consumption of what Monteiro later termed \u201cultra-processed foods\u201d alongside a <a href=\"https:\/\/journals.plos.org\/plosone\/article?id=10.1371\/journal.pone.0092752\" target=\"_blank\" rel=\"noopener\">parallel rise<\/a> in obesity and chronic diseases.<\/p>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">Ultra-processed foods, or UPFs for short, are those prepackaged foods that can be forgotten in your pantry seemingly forever and still taste great when you happen upon them. UPFs are your sodas, potato chips, granola bars, protein bars, protein powders, instant noodles, candy, and even most types of store-bought bread. These foods are already innately familiar to anyone who has ever stepped foot into a grocery store, a gas station mini-mart, or a fast food restaurant.<\/p>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">Today, the average American consumes some <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC5855172\/\" target=\"_blank\" rel=\"noopener\">60 percent<\/a> of their calories from ultra-processed foods; some <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/abs\/10.1111\/ijpo.12563\" target=\"_blank\" rel=\"noopener\">studies<\/a> found that number to be <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC9384846\/#:~:text=Conclusions:,2%2C3\" target=\"_blank\" rel=\"noopener\">higher<\/a> among children.

Studying the impacts of nutrition on human health is notoriously tricky given how so many factors \u2014 such as race, income, genetics, and the like \u2014 can play a role.

Ultra-processed foods, however, are made of ingredients that are extracted from whole foods through a series of industrial processing steps and then recombined with additives to give you this whole new food that\u2019s shelf-stable.<\/p>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">It seems that somewhere in all this food processing, food can become harmful. But the jury \u2014 or science, rather \u2014 is still out on exactly how that happens. Despite the still-emerging scientific evidence, it seems that reducing UPF consumption could improve your health. But, to make things more complicated, we live in a food environment where UPFs are not only aggressively marketed to us from a young age, but also are often the only affordable and accessible option for millions of people.<\/p>\n<div class=\"duet--article--block-placement _80slsf1 _80slsf0 duet--article--article-body-component\">\n<div id=\"what-are-ultra-processed-foods\" class=\"_7ka5u1 _7ka5u0 duet--article--standard-heading xkp0cg0\">\n<h2 class=\"duet--article--dangerously-set-cms-markup\"><strong>What are ultra-processed foods?<\/strong><\/h2>\n<\/div>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">Though we refer to UPFs as \u201cfoods,\u201d common definitions imply that they are more akin to chemical concoctions that happen to be edible.

Unless you work at a Michelin-starred restaurant or have some niche interest in gastronomy, you probably don\u2019t have maltodextrin or tartrazine sitting in your cupboards at home.<\/p>\n<\/div>\n<div class=\"duet--article--block-placement _80slsf1 _80slsf0 duet--article--article-body-component\">\n<div id=\"what-the-science-says-and-doesnt-say\" class=\"_7ka5u1 _7ka5u0 duet--article--standard-heading xkp0cg0\">\n<h2 class=\"duet--article--dangerously-set-cms-markup\"><strong>What the science says \u2014 and doesn\u2019t say<\/strong><\/h2>\n<\/div>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">The hard thing about nutrition science is that it\u2019s notoriously difficult to untangle all the different things that impact health on top of understanding why people make the food decisions they do. Where you grew up, how much money you make, and genetics can all factor into health and nutrition. Because of this complexity, researchers cannot design experiments where they manipulate each of these factors one by one and see what effect that has on health. Instead, scientists rely on observational studies, collecting demographic data and information about the dietary habits of participants including their UPF consumption.<\/p>\n<\/div>\n<div class=\"duet--article--article-body-component\">\n<p class=\"duet--article--dangerously-set-cms-markup duet--article--standard-paragraph _1agbrixh lg8ac51 lg8ac50 xkp0cg0\">But even collecting data on dietary habits is challenging. \u201cIn nutrition, what makes it even harder is that diet is so extremely complex,\u201d explained <a href=\"https:\/\/scholar.google.com\/citations?user=gsLuYa8AAAAJ&amp;hl=en\" target=\"_blank\" rel=\"noopener\">Filippa Juul<\/a>, a nutritional epidemiologist at New York University.<\/p>\n<p>For More News Update, Follow <a href=\"https:\/\/readnownews.in\/en\/\">Read Now News<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>These days, it seems like there is no end to things that can harm you: vaping, social media, sitting for long periods of time, too much sun, too little sun.
